LANSING, Mich. — Republican presidential candidate John McCain plans to hold an invitation-only town hall meeting Friday morning at the General Motors Technical Center in Warren.

The visit comes a week after the Arizona senator met with about 250 people at a campaign stop at auto supplier Bayloff Stamped Products in Wayne County's Van Buren Township. He'll start his swing through Michigan this week with a Thursday fundraiser at the Ferrysburg home of former ambassador Peter Secchia.

McCain spokeswoman Leah Yoon said the town hall meeting will give the Arizona senator a chance to talk about his incentives for next-generation vehicles and the need to move to new technology such as the Chevrolet Volt, a plug-in electric car that's being designed at the Technical Center. GM plans to have the Volt on the market by 2010.

"Senator McCain is committed to investing in jobs for the future. He believes that the U.S. must become a leader in what he's calling the new international jobs in the green economy," Yoon said.

Mitt Romney, a Michigan native and former Massachusetts governor who beat McCain in Michigan's GOP presidential primary before bowing out of the race, gave a pep talk to McCain workers Monday evening in Farmington Hills as he officially opened the McCain Great Lakes Regional headquarters overseeing Michigan, Wisconsin and Indiana.

Romney also gave interviews to national media probing his prospects as McCain's running mate.

McCain wants to offer a $5,000 tax credit to people who buy zero-emission cars and break the U.S. dependence on foreign oil by expanding domestic oil production. He also has proposed offering a $300 million government prize to whomever can develop an automobile battery that far surpasses existing technology.

The senator plans to take questions from technical center employees attending the event. The center, in Macomb County just north of Detroit, employs nearly 17,000 people, many of them engineers and designers.

McCain said last week in Michigan that U.S. auto workers have the ingenuity and skills to move to new types of vehicles as sales of profitable but gas-guzzling sport utility vehicles plunge and predicted the Volt "will create thousands and thousand of new jobs for Michigan." GM spokesman Greg Martin welcomed McCain's decision to come to the Technical Center, noting that it's a good way "for us to show what we're doing as far as advanced technology and a lot of our plans for strengthening our place in the market."

Martin added that the automaker has been pleased with the attention it has received from both McCain and his Democratic rival, Sen. Barack Obama.

Brent Colburn, Michigan Obama campaign spokesman, said McCain's focus on the auto industry won't help the state.

"We ... look forward to him once again explaining his support for the failed Bush economic policies that continue to cost Michigan jobs," Colburn said.
